Clinical spectrum of eye malformations in four patients with Mowat-Wilson syndrome.

Mowat-Wilson syndrome (MWS) is a rare genetic syndrome characterized by a specific facial gestalt, intellectual deficiency, Hirschsprung disease and multiple congenital anomalies. Heterozygous mutations or deletions in the zinc finger E-box-binding homeobox2 gene (ZEB2) cause MWS. ZEB2 encodes for Smad-interacting protein 1, a transcriptional co-repressor involved in TGF-beta and BMP pathways and is strongly expressed in early stages of development in mice. Eye abnormalities have rarely been described in patients with this syndrome. Herein, we describe four patients (two males and two females; mean age 7 years) with MWS and eye malformations. Ocular anomalies included, iris/retinal colobomas, atrophy or absence of the optic nerve, hyphema, and deep refraction troubles, sometimes with severe visual consequences. All eye malformations were asymmetric and often unilateral and all eye segments were affected, similarly to the nine MWS cases with ophthalmological malformations previously reported (iris/chorioretinal/optic disc coloboma, optic nerve atrophy, retinal epithelium atrophy, cataract, and korectopia). In human embryo, ZEB2 is expressed in lens and neural retina. Using the present report and data from the literature, we set out to determine whether or not the presence of eye manifestations could be due to specific type or location of mutations. We concluded that the presence of eye malformations, although a rare feature in MWS, should be considered as a part of the clinical spectrum of the condition.

Intravitreal dexamethasone implant versus anti-VEGF injection for treatment-naïve patients with retinal vein occlusion and macular edema: a 12-month follow-up study.

PURPOSE: The objective of his study was to compare the visual and anatomical outcomes in treatment-naïve patients with macular edema secondary to retinal vein occlusion after intravitreal injections of dexamethasone implants (DEX) and anti-VEGF. METHODS: One hundred two patients (64 in the anti-VEGF group, 38 in the DEX group) without previous treatment were included in this multi-center retrospective study and evaluated at baseline and 1, 3, 6, and 12 months after the onset of treatment. Patients were defined as "good responders" if central macular thickness (CMT) was less than or equal to 250 µm in TD-OCT or 300 µm in SD-OCT after the injections. RESULTS: At month 3 (n = 102), BCVA had increased significantly, by 0.1 ± 0.3 logMAR in the anti-VEGF group (p = 0.04) and 0.4 ± 0.4 logMAR in the DEX group (p < 0.001); the difference between the two groups was statistically significant (p = 0.007). CMT decreased significantly, by 138 ± 201 µm (-19 %, p < 0.001) in the anti-VEGF group and 163 ± 243 µm (-21 %, p < 0.001) in the DEX group. After 3 months, five patients (13 %) in the DEX group and 20 (31 %) in the anti-VEGF group (p < 0.001) changed treatment. Among the 77 patients who did not switch from their initial treatment, no significant functional or anatomical difference between the two groups was observed at months 6 and 12. Elevation of intraocular pressure > 21 mmHg was more frequent in the DEX group (21 %) than in the anti-VEGF group (3 %, p = 0.008). CONCLUSIONS: Visual acuity recovery was better in the DEX group than in the anti-VEGF group at month 3, but with no difference in CMT. In patients who did not change treatment, the long-term anatomical and visual outcome was similar between the DEX and anti-VEGF groups.

Body fat distribution and adipokine secretion are not associated with diabetic retinopathy in patients with type 2 diabetes mellitus.

AIMS: The link between diabetic retinopathy (DR) and adipokines is controversial. Some studies suggest that visceral fat and adipokines could be additional risk factors for DR. The aim of this study was to determine the relationship between abdominal fat or adipokine secretion and DR in patients with type 2 diabetes mellitus (DM). METHODS: A total of 179 patients with type 2 DM were included. Each patient underwent measurement of plasma adiponectin and leptin and an evaluation of body fat distribution (visceral and subcutaneous) with MRI. The severity of DR was evaluated according to the classification of the American Academy of Ophthalmology. Patients were classified in 3 groups: absence of DR, mild and moderate DR, and advanced DR (severe, proliferative and laser-treated DR). RESULTS: There were no significant differences between the 3 groups for adiponectin, leptin and visceral or subcutaneous fat accumulation. Patients with DR had a mean duration of diabetes, serum creatinine concentration and percentage of macroalbuminuria significantly higher than patients without DR (p < 0.001, p = 0.003 and p < 0.001, respectively). Serum adiponectin increased with the diabetic nephropathy stage (p = 0.007). CONCLUSIONS: Our study suggests that body fat distribution and adipokine secretion are not associated with DR in patients with type 2 DM.

A randomised study comparing performance and safety of Eyestil Plus® vs Vismed Multi® in moderate-to-severe dry eye syndrome patients.

PURPOSE: This clinical investigation compared the performance and safety of Eyestil Plus® (SIFI) and Vismed Multi® (TRB Chemedica) for reducing keratitis lesions in moderate-to-severe dry eye disease (DED) patients. MATERIALS AND METHODS: This was a randomised, double-blind, multicentre investigation. 96 adults (>18 years of age) with moderate-to-severe DED received Eyestil Plus® (N = 48) or Vismed Multi® (n = 48) 6 times daily for 3 months. The primary objective clinical performance after 1 month as global corneal and conjunctival staining scores. The secondary objectives were clinical performance after 3 months, tear film stability (tear break up time (TBUT), tear production (Schirmer test), patient-reported outcomes (PROs), investigator satisfaction, and safety. RESULTS: 96 participants were randomised to receive the clinical investigations' treatments, 82.3% of them were female and their mean age was 65.8 years. The non-inferiority of Eyestil Plus® for moderate-to-severe DED was demonstrated at 1 month. No statistical difference was found for any of the study's objectives: change at 1 and 3 months of the global corneal and conjunctival staining score (p-value = 0.506 and 0.661, respectively), change at 1 and 3 months (p-value = 0.538 and 0.302) for TBUT test; change at 3 months for Schirmer test (p-value = 0.540). There were no changes for PROs either. Investigator satisfaction was high for both products. 16.6% of the participants experienced adverse events. CONCLUSION: This clinical investigation showed the non-inferiority of Eyestil Plus® compared to Vismed Multi® regarding performance and safety in a moderate-to-severe DED population.

Training in cataract surgery in Spain: analysis of the results of a survey of the European Board of Ophthalmology in a Spanish cohort.

INTRODUCTION: A survey conducted by the European Board of Ophthalmology (EBO) revealed significant differences in the surgical training of the ophthalmology residents in Europe, including a disparity between the sexes and a variation in the experience on cataract surgery (CC) between them. This study is about the Spanish sub-cohort of the survey, and its objective is to present and analyse the peculiarities of ophthalmology training in Spain within the European context, as well as discussing ways to harmonise and improve that training throughout the EU. METHODS: We analyse data of the Spanish participants in the EBO exams, defining subgroups by the Autonomous Communities existing in Spain. RESULTS: 93 of 135 requested participants (68.9%) responded. A 60.2% passed the EBO exam between 2021 and 2022, being mostly women (65.59%) aged 31 years old on average. The 91.4% were right-handed, coming from 13 of the 17 Spanish autonomous communities, although mostly from the Community of Valencia, Madrid and Catalonia. Respectively, 16.1%, 3.2% and 8.7% of the respondents said they have completed 10 or more training sessions on animal eyes, synthetic eyes and through the virtual reality simulator. This training was correlated with greater self-confidence in the management of a posterior capsular tear during surgery (p .025). All respondents manifested to have already performed stages of the CC. The average number of operations reported was 181.6 with regional disparities. A significant difference is observed between the sexes against women (-28.3%, p 0.03). DISCUSSION: Ophthalmologists in Spain, much more than other European countries, have greater opportunities for surgical training, with surgical procedures during the residency, that nearly triples those made by the others. Spanish women refer, like their European colleagues, to be in disadvantage in learning opportunities about cataract surgery. The Simulation Based Medical Education (SBME) allows to respond to the training deficit and complements the training on the patient. Although we demonstrate a significant correlation between the number of procedures carried out and self-confidence to operate simple cases, the SBME would be a complementary tool in self-confidence in front of a complication like capsular rupture. CONCLUSION: Spain massively adopts the model named by us "surgery for all", despite the underrepresentation of women in this area, emphasising a need for cultural change that the SBME could facilitate.

[Retinal vascular network: Changes with aging and systemic vascular disease (cardiac and cerebral)]. / Caractéristiques vasculaires rétiniennes : modifications lors du vieillissement et en pathologie vasculaire systémique (cardiaque et cérébrale).

For over 10 years, the description of the retinal microvascular network has benefited from the development of new imaging techniques. Automated retinal image analysis software, as well as OCT angiography (OCT-A), are able to highlight subtle, early changes in the retinal vascular network thanks to a large amount of microvascular quantitative data. The challenge of current research is to demonstrate the association between these microvascular changes, the systemic vascular aging process, and cerebrovascular and cardiovascular disease. Indeed, a pathophysiological continuum exists between retinal microvascular changes and systemic vascular diseases. In the Montrachet study, we found that a suboptimal retinal vascular network, as identified by the Singapore I Vessel Assessment (SIVA) software, was significantly associated with treated diabetes and an increased risk of cardiovascular mortality. In addition, we supplemented our research on the retinal vascular network with the use of OCT-A. In the EYE-MI study, we showed the potential role of quantitative characterization of the retinal microvascular network by OCT-A in order to assess the cardiovascular risk profile of patients with a history of myocardial infarction. A high AHA (American Heart Association) risk score was associated with low retinal vascular density independently of hemodynamic changes. Thus, a better understanding of the association between the retinal microvasculature and macrovascular disease might make its use conceivable for early identification of at-risk patients and to suggest a personalized program of preventative care. The retinal vascular network could therefore represent an indicator of systemic vascular disease as well as an interesting predictive biomarker for vascular events.

[Management of ocular toxoplasmosis in France: Results of a modified Delphi study]. / Prise en charge de la toxoplasmose oculaire en France : résultats d'une étude Delphi modifiée.

OBJECTIVE: To evaluate diagnostic and therapeutic practices and then establish a consensus on the management of ocular toxoplasmosis in France through a Delphi study. MATERIALS AND METHODS: Twenty-three French experts in ocular toxoplasmosis were invited to respond to a modified Delphi study conducted online, in the form of two questionnaires, in an attempt to establish a consensus on the diagnosis and management of this pathology. The threshold for identical responses to reach consensus was set at 70 %. RESULTS: The responses of 19 experts out of the 23 selected were obtained on the first questionnaire and 16 experts on the second. The main elements agreed upon by the experts were to treat patients with a decrease in visual acuity or an infectious focus within the posterior pole, to treat peripheral lesions only in the presence of significant inflammation, the prescription of first-line treatment with pyrimethamine-azithromycin, the use of corticosteroid therapy after a period of 24 to 48hours, the prophylaxis of frequent recurrences (more than 2 episodes per year) with trimethoprim-sulfamethoxazole as well as the implementation of prophylactic treatment of recurrences in immunocompromised patients. On the other hand, no consensus emerged with regard to the examinations to be carried out for the etiological diagnosis (anterior chamber paracentesis, fluorescein angiography, serology, etc.), second-line treatment (in the case of failure of first-line treatment), or treatment of peripheral foci. CONCLUSION: This study lays the foundations for possible randomized scientific studies to be conducted to clarify the management of ocular toxoplasmosis, on the one hand to confirm consensual clinical practices and on the other hand to guide practices for which no formal consensus has been demonstrated.

Methanol poisoning: two case studies of blindness in Indonesia.

We report two recent cases of methanol intoxication in French patients living in Bali. These intoxications were secondary to the consumption of adulterated liquor. Both patients presented acute bilateral loss of vision a few days after methanol ingestion with no sign of recovery. The fundus showed bilateral optic atrophy that was well correlated with retinal nerve fibre layer thickness measured with spectral-domain optical coherence tomography and compatible with toxic optic neuropathy. In one of the patients, macular swelling in one eye was observed. Electroretinograms were normal contrasting with abolished visual evoked potentials. Methanol was isolated from a sample of the beverage with gas chromatography. Methanol intoxication may occur in Asia and therefore adequate information for tourists and the local population is required.

[Treat-and-extend anti-angiogenic protocol in clinical practice for patients with exudative age-related macular degeneration: Consensus of French experts]. / Consensus d'experts français sur la mise en œuvre pratique du régime Treat-and-Extend par anti-angiogéniques chez les patients atteints de DMLA exsudative.

Optimizing treatment regimens for anti-angiogenic drugs is now a major issue in the management of patients with exudative AMD. The evolution of these approaches has led retinologists to favor so-called proactive administration regimens, such as Treat-and-Extend (T&E), which make it possible to anticipate recurrence and to plan intravitreal injections of anti-angiogenic drugs in advance. Nevertheless, a real need to standardize the application of this regimen has been identified. This article proposes a consensus based on the Delphi methodology, which might provide a guide for ophthalmologists to manage patients with exudative AMD using the T&E protocol. While some aspects remain debated to date, this article provides elements to guide the implementation of T&E. The experts recommend that a loading dose of 3 monthly injections should be administered before starting T&E. They also recommend adjusting the reinjection intervals by±2 weeks in a standardized fashion. The intervals are then decreased in the presence of anatomical and/or functional deterioration, maintained when the interval of recurrence is identified, and increased when anatomical and/or functional improvement is observed. A maximum interval between 3 and 4 months is recommended by the experts, with maintenance of the maximum interval for 1 year before considering a possible exit from the T&E protocol. In the event of a significant decrease in visual acuity related to the disease along with significant anatomical degradation, it is recommended to restart monthly injections. In the case of bilateral disease, when synchronized timing of injections for both eyes is desired, the experts recommend using the shorter of the two intervals.

Effects of oxysterols on cell viability, inflammatory cytokines, VEGF, and reactive oxygen species production on human retinal cells: cytoprotective effects and prevention of VEGF secretion by resveratrol.

BACKGROUND AND AIMS: Oxysterols are assumed to play important roles in age-related macular degeneration, a major cause of blindness. So we characterized the cytotoxic, oxidative, inflammatory, and angiogenic activities of oxysterols (7ß-hydroxycholesterol (7ß-OH), 7-ketocholesterol (7KC), 25-hydroxycholesterol (25-OH)) in human retinal ARPE-19 cells, and evaluated the protective effects of resveratrol (Rsv: 1 µM), a polyphenol from red wine. METHODS: ARPE-19 cells were treated with 7ß-OH, 7KC, or 25-OH (5-40 µg/mL; 24-48 h) without or with Rsv. Cell viability was determined using trypan blue and the MTT assay. Cell death was characterized by electron microscopy and in situ detection of activated caspases with fluorochrome-labeled inhibitors of caspases. Reactive oxygen species (ROS) production was measured with hydroethidine. ELISA methods and a cytometric bead assay were used to quantify cytokines involved in inflammation (IL-8, IL-1ß, IL-6, IL-10, IL-12p70, TNF-α, MCP-1) and VEGF. RESULTS: 7ß-OH and 7KC triggered a caspase-independent cell death process associated with the presence of multilamellar cytoplasmic structures evocating phospholipidosis, increased ROS production, and IL-8 secretion. 7ß-OH enhanced VEGF secretion. No cytotoxic effects were identified with 25-OH, which highly stimulated ROS production, MCP-1, and VEGF secretion. With oxysterols, no IL-10, TNF-α, and IL-12p70 secretion were detected. 25-OH induced IL-8 secretion through the MEK/ERK½ signaling pathway, and Rsv showed cytoprotective activities and inhibited VEGF secretion. CONCLUSION: 7ß-OH, 7KC, and 25-OH have cytotoxic, oxidative, inflammatory, and/or angiogenic activities on ARPE-19 cells. As Rsv has some protective effects against oxysterol-induced cell death and VEGF secretion it could be valuable in ARMD treatment.

Evaluation of the Spot Vision Screener in comparison with the orthoptic examination in visual screening in 3-5 year-old schoolchildren.

PURPOSE: To evaluate the Spot Vision Screener (SVS) compared with the orthoptic examination for detection of amblyopia risk factors in preschools. METHODS: This prospective study included children with a visual screening organized by the department of "le" (PMI) in Côte d'Or (Burgundy, France), between June 2017 and April 2018. All children were evaluated with the SVS followed by a clinical orthoptic examination. Results with the SVS were compared with those obtained by clinical orthoptic examination. RESULTS: A total of 1236 subjects were included in the study from 100 preschools. The mean age of the children was 3.6±0.7 years, and 627 were female (50.7%). The orthoptic examination detected 308 (24.9%) children with subnormal visual acuity for age in one eye or both. In children with a history of prematurity, the orthoptic examination was more frequently abnormal (P=0.002), which was not seen with the SVS (P=0.050). The SVS screened 20 (1.6%) children with strabismus, while 40 (3.2%) were detected by orthoptic examination. At the end of the screening, the SVS detected 182 (14.7%) suspect patients while 311 (25.1%) suspect patients were detected after the orthoptic examination. Comparing SVS with orthoptic examination, agreement was fair (κ=0.4). CONCLUSION: The SVS can be a useful device for visual screening, but agreement with the orthoptic examination was only fair. The Spot vision screener should be used in conjunction with a clinical orthoptic examination.

Twelve-month outcomes of intra-vitreal anti-VEGF agents for treatment-naïve neovascular age-related macular degeneration eyes: French data from the fight for retinal blindness!

INTRODUCTION: To describe the one-year functional outcomes of treatment-naïve neovascular age-related macular degeneration (nAMD) treated with anti-VEGF agents at the Dijon University Hospital Ophthalmology Department. METHODS: Real-life interventional study including all treatment-naïve nAMD patients from January 2016 to December 2018 in the Ophthalmology Department of Dijon University Hospital. Data were retrospectively collected from the Fight Retinal Blindness! (FRB!) registry. At baseline, medical history, visual acuity (VA), type of lesion and activity on angiography and optical coherence tomography (OCT), and treatment were recorded. On follow-up, VA, lesion activity and treatment were recorded. RESULTS: Three-hundred twenty eyes of 259 patients were included, of which 65.6% were female and with a mean age of 80.1±11.1 years. Mean VA (standard deviation, SD) at baseline was 53.2 ETDRS letters (25.3). All patients received anti-VEGF injections, of which 164 eyes (51.2%), 152 eyes (47.5%) and 4 eyes (1.2%) were treated with aflibercept, ranibizumab and bevacizumab, respectively. A total of 198 eyes of 169 patients completed the 12-month follow-up, with a median (first quartile, third quartile) of 12 visits (10, 13). At one year (n=198), the overall mean VA gain [95% CI] was +3.3 ETDRS letters [0.7, 5.9] and 173 (87.4%) of the treated eyes did not lose 15 or more letters. We found no statistically significant difference in mean VA gain between aflibercept and ranibizumab. CONCLUSION: This real-world study confirmed the efficacy of anti-VEGF agents in nAMD and the feasibility of analyzing data in an international registry.

Efficacy and follow-up of anti-VEGF injections in diabetic macular edema in real-life practice at the Dijon university medical centre through the Save Sight Registries.

PURPOSE: To evaluate the efficacy of intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections (IVT) in diabetic macular edema (DME) in real-life practice using the Save Sight Registries (SSR). MATERIAL AND METHODS: We conducted an observational, single-centre, retrospective study in the department of ophthalmology of the Dijon University Hospital. We included treatment-naive patients who presented with DME between January 2016 and December 2017. Demographic and clinical data, follow-up visits, and treatments administered were entered into the SSR, an international online ophthalmic registry. Primary endpoints were the change in best-corrected visual acuity (BCVA) and central subfield thickness (CST) from baseline to 12 and 24 months. RESULTS: Fifty-eight eyes of 43 patients with a mean [standard deviation (SD)] age of 67.1 [9.5] years were included. Forty-one eyes completed 12 months of follow-up, and 17 eyes completed 24 months of follow up. Median [SD] baseline BCVA was 56.1 [22.9] ETDRS letters and the median [95% confidence interval (95% CI)] baseline CST was 447.9 [161.0] micrometers (µm). Median [95% CI] improvement in BCVA from baseline to months 12 and 24 were respectively, +5.6 [+0.5; +10.7] ETDRS letters and +7.7 [-2.8; +18.2] ETDRS letters. The median [95% CI] decrease in CST from baseline to months 12 and 24 were respectively, -110.9 [-154.5; -67.3] µm and -125.5 [-198.0; -53.0] µm. CONCLUSION: Our clinical practice can be evaluated easily with the SSR system. In real life, anti-VEGF IVT are an effective treatment for DME, which result in improved BCVA and decreased CST.

Influence of cardiac hemodynamic variables on retinal vessel density measurement on optical coherence tomography angiography in patients with myocardial infarction.

INTRODUCTION: Quantitative measurements of retinal microvasculature by optical coherence tomography angiography (OCT-A) have been used to assess cardiovascular risk profile. However, to date, there are no studies focusing on OCT-A imaging in the setting of the altered hemodynamic status found in high-risk cardiovascular patients. METHODS: To determine the potential association between retinal vascular density on OCT-A and a comprehensive battery of hemodynamic variables in patients with myocardial infarction (MI) using data from the acute phase and at 3 months follow-up after cardiac rehabilitation. This prospective longitudinal study included patients who presented with MI in the cardiology intensive care unit at Dijon University Hospital. Main outcomes and measurements were retinal vessel density on OCT-A, hemodynamic status based on left ventricular ejection fraction (LVEF), and indexed cardiac output during the acute phase of myocardial infarction and at 3 months follow-up. RESULTS: Overall, 30 patients were included in this pilot study. The median (IQR) age was 64 years (55-71) with 87% men. At admission, the mean (SD) LVEF was 53% (11), and the mean indexed cardiac output was 2.70 (0.83) L/min/m2. On OCT-A, the mean inner retinal vascular density was 19.09 (2.80) mm-1. No significant association was found between retinal vascular density and hemodynamic variables. CONCLUSION: We found no significant association between retinal vascular density on OCT-A and hemodynamic variables in the acute phase of a myocardial infarction or after 3 months of cardiac rehabilitation. Therefore, OCT-A findings do not seem to be influenced by the hemodynamic changes associated with myocardial infarction.

Screening for diabetic retinopathy in a rural French population with a mobile non-mydriatic camera.

AIM: The aim of this study was to evaluate the yield of diabetic retinopathy (DR) screening in a rural population using a mobile non-mydriatic camera. METHODS: The 72 least medicalized areas of Burgundy were the target areas. An orthoptist took fundus photographs using a Topcon TRC-NW6S non-mydriatic camera (four fields: posterior pole; nasal; temporal; and upper). Interpretations were done in the Department of Ophthalmology according to the classification of the French Language Association for the Study of Diabetes and Metabolic Diseases (Alfediam). RESULTS: Between 2004 and 2006, 1974 diabetics were screened-676 the first year, and 1298 in the second. The rate of non-interpretable photographs was 13%. Of the 1974 screened patients, there were 103 cases of DR (5.2%), comprising 70 mild non-proliferative DR (68%), 21 moderate non-proliferative DR (20.4%) and 12 severe non-proliferative DR (11.6%). The mean age of the patients with a DR was 66.7+/-10.9 years, with a mean duration of diabetes of 16.5+/-9.8 years. Only 35 (34%) patients were aware of their HbA(1c), which had a mean value of 7.8% and 19 had visited an ophthalmologist in the year before screening (18.4%). After the initial screening, 90,5% of the patients consulted an ophthalmologist as recommended. CONCLUSION: Screening improved the quality of the ocular follow-up in diabetics in this rural area. However, improvements in management are needed to lower the cost of such a programme.

Approche diagnostique et thérapeutique de la vasculopathie polypoïdale choroïdienne. Recommandations de la Fédération France Macula.

PURPOSE: To update the medical literature on the diagnostic and therapeutic approach to polypoidal choroidal vasculopathy (PCV) and to propose a treatment algorithm in agreement with French market approval, supported by the France Macula Federation (FFM). METHODS: Literature review and expert opinion. RESULTS: The diagnosis of PCV is based on multimodal imaging, including indocyanine green angiography (ICGA), which is considered the gold standard for the diagnosis of PCV. Regarding the therapeutic management of PCV, the FFM recommends treating PCV first-line either by monotherapy with intra-vitreal anti-vascular endothelial growth factor (anti-VEGF) injections, or by a combined treatment of photodynamic therapy (PDT) with Verteporfin and intra-vitreal anti-VEGF injections, depending on the location of the PCV.

Visual outcomes and complications of congenital cataract surgery.

PURPOSE: To describe the visual results and postoperative complications of congenital cataract surgeries performed between 2005 and 2016. METHODS: A retrospective consecutive case series of congenital cataract surgeries was carried out at the Dijon University Hospital in France. Intraocular lens implantation was primary or secondary according to age. Pre- and post-operative assessment was performed through ophthalmologic consultations with orthoptic measurements. Visual function and adverse events were recorded. RESULTS: Fifty-six consecutive procedures were evaluated in 37 infants. Overall, 26.8% of patients had unilateral cataracts, and 73.2% had bilateral cataracts. Median age at surgery was 1.0 years [IQR (interquartile range): 0.3-5.2] and 2.7 years [IQR: 0.4-9.5] for unilateral and bilateral cataracts, respectively. Median best-corrected visual acuity (BCVA) at the last follow-up was 0.5logMAR [IQR: 0.2-0.8] and 0.1logMAR [IQR: 0.0-0.8] for the unilateral and bilateral group, respectively. Posterior capsule opacification (PCO) was the primary postoperative complication: 60.0% in unilateral cataract and 46.3% in bilateral cataracts (P=0.019). Median follow-up was 2.0 years [IQR: 1.0-5.0]. CONCLUSION: Congenital cataract surgery appears to be safe and effective when combined with early, conscientious amblyopia treatment. Bilateral congenital cataracts had better visual outcome than unilateral cataract.

Influence of rosuvastatin on the NAD(P)H oxidase activity in the retina and electroretinographic response of spontaneously hypertensive rats.

BACKGROUND AND PURPOSE: Retinal complications may be encountered during the development of hypertension as a response to oxidative stress. Statins may reduce the risk of developing hypertension and ocular diseases. We evaluate the effects of rosuvastatin (ROSU) on retinal functionality and oxidative stress levels in normotensive and spontaneously hypertensive rats (SHR). EXPERIMENTAL APPROACH: Wistar Kyoto (WKY) and SHR were treated for 3 weeks with rosuvastatin (10 mg kg(-1) day(-1)). Electroretinograms (ERG) were recorded before and after rosuvastatin treatment. Reactive oxygen species (ROS) were determined in the retina with dihydroethidium staining and NAD(P)H oxidase activity was evaluated. KEY RESULTS: Retinal ganglion cell ROS and retinal NAD(P)H oxidase activity were higher in SHR than in WKY rats, respectively (17.1+/-1.1 vs 10.2+/-1.2 AU, P<0.01; 38095+/-8900 vs 14081+/-5820 RLU mg(-1); P<0.05). The ERG b-wave amplitude in SHR was significantly lower than that in WKY rats. Rosuvastatin reduced SBP in SHR but did not change plasma lipid levels. Rosuvastatin treatment in SHR significantly decreased ROS levels (11.2+/-1.3, P<0.01), NAD(P)H activity in retinal ganglion cells (9889+/-4290; P<0.05), and increased retinal plasmalogen content in SHR, but did not modify the ERG response. CONCLUSIONS AND IMPLICATIONS: Rosuvastatin, beyond lowering cholesterol levels, was able to lower ROS in the retina induced by hypertension, but without improving retinal function in SHR. These findings point to a complex relationship between ROS in the pathogenesis of retinal disease and hypertension.
